Set-Content - PowerShell 1.0
Microsoft Windows PowerShell is a command-line shell and scripting tool based on the Microsoft .NET Framework. It is designed for system administrators, engineers and developers to control and automate the administration of Windows and applications.
More than hundred command-line tools (so called "cmdlets") can be used to perform system administration tasks and Windows Management Instrumentation (WMI). These cmdlets are easy to use, with standard naming conventions and common parameters, and standard tools for piping, sorting, filtering, and formatting data and objects.
Set-Content
Description
Back up your Hyper-V VMs Easy & Fast. 100% built for Hyper-V. Free for 2 VMs, forever.
Usage
Options
-path string
The path to the item that will receive the content.
Wildcards are permitted.
-literalPath string
Like Path above, only the value is used exactly as typed.
No characters are interpreted as wildcards. If the path includes any
escape characters then enclose the path in single quotation marks.
-value Object
The new content for the item.
-include string
Change only the specified items in the Path.
Wildcards are permitted. e.g. "*.txt"
-exclude string
Omit the specified items.
Wildcards are permitted. e.g. "*.log"
-filter string
A filter in the provider's format or language.
The exact syntax of the filter (wildcard support etc) depends on the provider.
Filters are more efficient than -include/-exclude, because the provider
applies the filter when retrieving the objects, rather than having
PowerShell filter the objects after they are retrieved.
-passThru
Pass the object created by Clear-Variable through the pipeline.
(By default this switch is not set)
-force
Override restrictions that prevent the command from succeeding, apart
from security settings. e.g. Force will create file path directories
or override a files read-only attribute, but will not change file permissions.
-credential PSCredential
Present a user/password credential to validate access to the file.
This is not yet supported in any Windows PowerShell core commands.
-whatIf
Describe what would happen if you executed the command without actually
executing the command.
-confirm
Prompt for confirmation before executing the command.
CommonParameters:
-Verbose, -Debug,-ErrorAction,-ErrorVariable, -OutVariable.
Example(s)
Write a string into a text file:
PS C:\>Set-content -path C:\test.txt -value "Hello World"
Write the current date into a CSV file:
PS C:\>get-date | set-content C:\Test_date.csv
Edit-Replace some text in every line of the file foo.txt :
PS C:\>(get-content foo.txt) | foreach-object {$_ -replace "oldTxt", "newTxt"} | set-content foo.txt
The parentheses around (Get-Content) ensure that the Get operation is completed before the Set operation begins, wthout this the two functions would both try to access the file at the same time.
